The DSC1033BI1-125.0000T: Frequency stability is ±50 ppm — adequate for clocking an MCU or FPGA without a PLL calibration cycle, though not tight enough for a precision Ethernet or USB reference.
This makes the oscillator suitable for battery-operated equipment that spends most of its life in sleep and wakes to a stable 125 MHz clock.
Microchip lists the DSC1033BI1-125.0000T as Obsolete.
Yes, Microchip lists the product status as Obsolete. No pin-compatible replacement has been announced by the manufacturer. Existing designs that require this exact order code must source from surplus inventory.
Yes, the part includes a Standby (Power Down) function. When the enable pin is pulled low, the output is disabled and the supply current falls to 1 µA max.
